The urban areas of Bhubaneswar and Cuttack are about 0.75 degree Celsius and 1.22 degree Celsius warmer than the surrounding rural areas.
The core city area is warmer than the recently developed suburban regions.
While there has been an increase in relatively cooler regions over these cities during daytime, the reverse is seen during night time.
During the night, both cities have been witnessing increased urban heat island effect
It is not clear why there is a decline in daytime land surface temperature
This decline may be due to multiple reasons, but we have still not explored them.
They may be due to an increase in clouds, increased air pollution/haziness, increased vegetation or any other things.
Further analysis is required to determine the major factors driving such changes.
But warming during night time is only affected by heat emitted by surface.
